Answer: $x=-14$

Step-by-step explanation:

Get rid of parentheses: $-2x-5-23=0$

Add all the numbers together, and all the variables: $-2x-28=0$

Move all terms containing x to the left, all other terms to the right:

$-2x=28$

$x=28/-2$

$x=-14$

Determine the ordered pair that satisfies the equation, 6x - 3y = 5.

Kazeer [188]

Given the equation $6x-3y=5.$

Check all options:

A. $\left(9,\dfrac{16}{3}\right)$ , this means that $x=9, y=\dfrac{16}{3}.$ Substitute these numbers into the left side of the equation equation:

$6\cdot 9-3\cdot \dfrac{16}{3}=54-16=38\neq 5.$

This option is false.

B. $\left(6,-3\right)$ , this means that $x=6, y=-3.$ Substitute these numbers into the left side of the equation equation:

$6\cdot 6-3\cdot (-3)=36+9=45\neq 5.$

This option is false.

C. $\left(1,-\dfrac{11}{3}\right)$ , this means that $x=1, y=-\dfrac{11}{3}.$ Substitute these numbers into the left side of the equation equation:

$6\cdot 1-3\cdot \left(-\dfrac{11}{3}\right)=6+11=17\neq 5.$

This option is false.

D. $\left(-2,-\dfrac{17}{3}\right)$ , this means that $x=-2, y=-\dfrac{17}{3}.$ Substitute these numbers into the left side of the equation equation:

$6\cdot (-2)-3\cdot \left(-\dfrac{17}{3}\right)=-12+17=5.$

This option is true.

Answer: correct choice is D.
